FT93C46A-ISR-T

Overview

The FT93C46A-ISR-T is a non-volatile EEPROM memory IC manufactured by Fremont Micro Devices Ltd. It features a 1Kbit storage capacity organized as 128 x 8 or 64 x 16 bits. The device utilizes a 3-wire serial interface with a maximum clock frequency of 2 MHz. It operates within a supply voltage range of 1.8V to 5.5V and supports an operating temperature range of -40°C to 85°C (TA). The component is housed in an 8-SOP surface-mount package.

Feature Summary

Provides non-volatile data retention for embedded applications
Supports high-speed 3-wire serial communication
Compatible with low-voltage power supplies down to 1.8V

Applications

Embedded systems requiring compact non-volatile storage
Industrial control units operating in extended temperature ranges
Consumer electronics utilizing low-voltage logic interfaces

Procurement Notes

Verify the specific suffix 'ISR' confirms the 8-SOP surface-mount package and 2 MHz speed rating. Confirm RoHS3 compliance status for environmental regulations. Ensure the supplier documentation matches the Fremont Micro Devices Ltd part number exactly, as variations exist within the 93C46A family regarding package type and voltage specifications.

Selection Notes

Select this component when a small footprint 8-SOP package is required for 1Kbit EEPROM storage. It is suitable for designs needing operation at voltages as low as 1.8V. Consider the 2 MHz interface speed for faster data access compared to standard 1 MHz variants. Verify that the 3-wire serial protocol aligns with the host controller's available pins.

Part Context

This part belongs to the FT93C46A series, which are pin-compatible replacements for industry-standard 93C46 devices. The series offers various package options including DIP, TSSOP, and SOP. The FT93C46A-ISR-T specifically denotes the surface-mount SOP variant with enhanced speed capabilities compared to older generation equivalents.
